CAP 1188 - no reaction to touch of C* pins. Expected behaviour?

And indeed it now works.

For info the steps are :

1) Set up the attached cables etc. before powering on as the chip calibrates everything on power up.
2) reset the status registers and int status e.g. via
i2cset -y 1 0x29 0x00 0
3) set up the leds to be linked to input stimuli
i2cset -y 1 0x29 0x72 255
4) set the led mode to "breathe" - top bits / bottom bits
i2cset -y 1 0x29 0x82 255
i2cset -y 1 0x29 0x81 255
5) wave you hand near the device and watch the leds react.
